Product Description

White Aluminum Oxide Grain Abrasive Sandblasting Media White Fused Alumina

White Fused Alumina (WFA or WA) is an important raw material for advanced refractories and abrasives, a widely used raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding, and hundreds of other applications. As it is a very pure, low iron alumina, specific refractory applications include high tech refractory castables, isostatic pressed refractories, and pre-cast refractory shapes. The benefits of White Fused Alumina in these applications are high alumina content, low impurities, and stability at high temperatures. 

White fused alumina is manufactured by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000 degree Celsius followed by a slow solidification process. The cooled crude is further crushed. The crushed crude is the semi-product. Then, the semi-product receives high intensity magnetic treatment to remove virtually all of the magnetic iron present. Air washing is also applied to the semi-product, to ensure the cleaness of the white fused alumia. Finally, the semi-product is sieved and classified into different grain sizes.

White fused alumina application:

1. Refractory materials .

2. Sandblasting - moderate hardness, high accumulation density, greater than major, toughness;

3. Free grinding -- free grinding in the fields of picture tube, optical glass, crystal glass and jade;

4. Resin grinding tools -- suitable for color, good hardness and toughness, applied to resin grinding tools;


Features of WFA White Fused Alumina

1.High Alumina
White Fused Alumina has a Aluminium Oixde(Al2O3) content of more than 99%.

2.Little Impurities
White Fused Alumina has very little impurities, usually less than 0.4% Na2O, less than 0.15 SiO2 and less than 0.15 Fe2O3.

3.High Hardness
The high content of Al2O3 (Aluminum Oxide) makes it to be with very high hardness (Mosh Hardness≥9)

4.Sharp Edges
White Fused Alumina is a crystal mineral with sharp edges and widely used in sandblasting,cutting and grinding abrasives.
